Theists joke often and say, well during sex what do atheists scream out?

I would answer, if the lover is very very good, we scream out their name! And since we're talking atheists here, who's partner may not be one, it tends to confuse those peepers looking down from Heaven.

Yeah atheists don't have a bias on sexual behavior so I would guess they have more fulfilling sex lives. Also , there's no guilt associated with sex and lust.
Still , at the moment, I'm as dry as a desert ...
